Hydrogen peroxide for water storage?greenspun.com : LUSENET : TimeBomb 2000 (Y2000) : One Thread
Can anyone tell me where I can find information on using hydrogen peroxide for long term water storage? I need details such as how much H2O2 per gallon, how long will the water keep, etc.
I already know about using bleach and stabilized oxygen. I just need the info on hydrogen peroxide. Thanks.

Yes, hydrogen peroxide can be used to purify water. I am unsure as to the amount needed per unit of water. Quoting from an internet source on water purification "Hydrogen Peroxide can be used to purify water if nothing else is available. Studies have shown of 99 percent inactivation of polio virus in 6 hr with 0.3 percent hydrogen peroxide and a 99 percent inactivation of rhinovirus with a 1.5% solution in 24 minutes. Hydrogen Peroxide is more effective against bacteria, though Fe+2 or Cu+2 needs to be present as a catalyst to get a reasonable concentration-time product."
My wife claims that she heard about using hydrogen peroxide for water purification when she was in the Girl Scouts, but she can't remember the amount needed. Any Girl Scouts or chemists out there with an answer?

A good source of relatively distilled water is rain water off your roof or a big collector. You will still want to filter out any particles from the shingles and might want to treat it with a little bleach when storing it and again just before drinking it. I prefer using hydrogen peroxide rather than bleach in drinking water if it is clean and clear. For water that is more suspect, use the iodine based water purification tablets. H2O2 a little more expensive, but less potentially harmful. You will need to use more like a teaspoon per 2 liters rather than a few drops.
I found this on Lycos.
